Red Algae share the characteristics of mechanism of nutriti

Red Algae share the characteristics of ___________ (mechanism of nutrition) and the photosynthetic pigment _______ with Green Algae as it does with other alga. However they so not share the characteristics of _________ (a photosynthetic pigment) specifically for the green algae group named ___________ structural and functional similarities with modern plants.

heterotrophy – chlorophyll b, chlorophyll b – Spirogyra.

Carrageenan – fucoxanthin, chlorophyll a -- Laminaria

autotrophy – chlorophyll a, chlorophyll b – Charophyta.

phycocyanins – phycoerythrin, chlorophyll a – Chloropyta.

Diatoms and Brown Algae are both ______. But are grouped in a common clade because of the similarity of their ______ and this structure’s ____-like projections when present.

Photosynthetic – flagella – hair-

Brown or golden – photosynthetic structures – amoeba-

autotrophic – body forms --  pennate or centric-

Question 7

Amoebozoans include both _________ and __________. The second group was once classified as __________. But are now placed in this clade because among other characteristics they are __________ (mechanism of nutrition) like amoeba.

Red algae and Green algae – plants autotrophic

Zygomycota and Ascomycota – fungi -- heterotrophic

Slime Molds and Oomycetes – fungi -- heterotrophic

Amoebae and Slime Molds (mycetozoans) – fungi and animals – phagotrophic.

Question 8

The clade Euglenozoa includes organisms such as Trypanosoma and ________ a common type of structure for locomotion.

Euglena with a flagellum

Paramecium with cilia

Plankton in fresh water or oceans

The vertebrae hosts of these organisms

Question 9

Table 1 on p. 63 outlines four Supergroups, of which one is the Alveolates. Identify two groups within the Alveolates and their shared common characteristics.

2. Formaniniferas and Radiolarians with a test shell

1.Ciliates and Dinoflagellates with alveoli sacs below the cell membrane

4. Euglena with flagella for locomotion

3. Red and Brown algae with air sacks for flotation

Solution

Red Algae share the characteristics of autotrophy (mechanism of nutrition) and the photosynthetic pigment chlorophyll a with Green Algae as it does with other alga. However they so not share the characteristics of chlorophyll b (a photosynthetic pigment) specifically for the green algae group named charophyta structural and functional similarities with modern plants.

The correc toption is...................3. autotrophy – chlorophyll a, chlorophyll b – Charophyta.
